This converter is used for high-power DC motor control and can be applied in different branches of industry. The converter has 12-pulse rectification circuit which is implemented on the basis of two three-phase thyristor bridges (thyristors are manufactured by Semikron). The converter gives an opportunity of operation with two armatures connected in parallel. For this purpose the converter is equipped with two exciters and two EMF regulators. This helps balance loads between armatures during operation.
Guaranteed service life is 12 months from putting into operation, but no longer than 18 months from delivery date.
